Im trying to implement Play Services in my app, Ive created an achievment on developer console and implemented everything. I havent uploaded the apk on the console or signed it. When I run the game on my phone the google play games dialog shows, but i think does not authenticate as the code in the lambda expression does not run, and I get the error (ReportProgress can only be called after authentication). Note: ReportProgress is called much later than authentication. Im wondering if this is due to the app not signed and uploaded to the console? because ive double-checked everything I cant find any problems. Anyone who has used Play services can help?
